That is super cool!
I don't really like the idea of the virtual shopping to go with it, you might miss all the best shops if you stick to the main shopping areas
. Whats wrong with a searchable database eh!
I can't really see Earthmine one with all the extras really benefitting the general public more than google, (read, those who pay more could get more coverage?), but I can see the use for businesses for many things. I spose you could work out distances of things, when house buying, but not so much day to day.
